ABUNDANCE CHART FOR BIRDS OF CENTRAL
AND SOUTHERN CALIFORNIA

There are two bar-graphs on this website, one is focused on land trips and the other is focused on pelagic trips. For the pelagic abundance bar-graph, please check the Pelagic link on this site.

The following bar graph will assist you in planning your trips for birding California. It will show you when you will most likely find your target birds, so you can plan your vacation accordingly. This chart is based on years of data and work by many great ornithologists, such as Kimball Garrett, Jon Dunn, Guy McCaskie, Dick Erickson and Paul Lehman. Keep in mind that this bar-graph is oversimplified and not intended to stand entirely by itself. For more detailed information, you may want to look at the bar-graph in ABA’s “A Birder’s Guide to Southern California” by Brad Schram.

It is possible that one of your targets may be common on the coast but another target may not be found on the coast. Perhaps the other target will be common in the mountains or in the desert. Some of your targets may be found in winter, but you may need another seasonal trip for a different target bird.

I have divided the key into five groups: Common, Fairly Common, Uncommon, Rare but Regular, and Rare but Irregular.
